Fessenden Lagoon Wastewater Treatment Plant, Wells County, North Dakota

Fessenden Lagoon is a wastewater treatment facility located in Wells County, North Dakota, serving a small community of 479 residents. The plant provides secondary treatment, a standard level for small agglomerations in the United States, ensuring that effluent meets basic environmental standards before discharge. Under the US Clean Water Act, facilities of this scale are typically permitted through the National Pollutant Discharge Elimination System (NPDES), which sets limits on pollutants to protect water quality. The plant's designed capacity of 378.54 cubic meters per day and current discharge volume of 227.13 cubic meters per day indicate it operates below capacity, allowing for future growth. The treated wastewater is discharged into local streams that drain into the James River basin, part of the larger Missouri River watershed. This region supports agricultural activities and provides habitat for aquatic species. Proper treatment helps maintain water quality in downstream ecosystems, including the Missouri River and ultimately the Gulf of Mexico.

The plant discharges into tributaries of the James River, which flows into the Missouri River and eventually the Mississippi River, reaching the Gulf of Mexico. This watershed supports diverse aquatic life and is important for regional agriculture. Secondary treatment reduces organic pollutants and suspended solids, protecting downstream water quality and ecosystems.
